Google Now Flight Reminders Too Late?

Google announced yesterday on Google+ that not only will Google Now show you your boarding passes and flight status but also tell you when it is time to leave to the airport, so you won't miss your flight. It has had this feature for a while, I believe.

The ironic part is, about an hour before Google posted that on Google+, a frequent flyer posted a complaint on Google Web Search Help that Google Now's reminder was way too late.

It gave this flyer an hour to drive to the airport, go through security and catch the flight. This is what he had to say:

For my flight today I'm looking at Google Now and it's telling me to leave at 5:53 for a 7:10 PM flight. I know that it takes just under 20 minutes without traffic, but given that its rush hour, I know that drive will be more than 40 minutes. PLUS I need to park my car. If I make it and TSA Precheck saves me life, I can see that I'll still be bolting to the gate during the end of boarding.
